Abstract
A mutation coordinator processes in-flight file operations in a role mutable file system to provide high availability data storage and uninterrupted network request processing. The mutation coordinator uses a container with data received from in-flight operations as they progress past checkpoints to enable the file system to seamlessly mutate between server and client operational roles. The checkpoint functions determine whether the operation should halt at the checkpoint when a mutation begins and log information in the container to reflect the progress of the operation. The halted operations are then completed on the new server when the mutation is complete.
